Letters Patent No. 108,865, dated November 1, 1870.

IMPROVEMENT IN CQRN'PLANTERS.

The Schedule referred to in these Letters Patent and making part of thesame To whom it may concern Be it known that I, CHARLES WISDOM, of FlatRock, in the county of Wayne and State of Michigan, have invented a newand useful Improvement in Corn-Planter; and I do declare that thefollowing is a true and accurate description thereof, reference beinghad to the accompanying drawing, and to the letters of reference markedthereon, and being a part of this specification, in which- Figure l is aside elevation of my device.

,Figure 2 is a section of the same, being a plan or top view of oneside, or half of the implement.

Figure 3 is a detached view of the dropper.

Similar letters of reference indicate corresponding parts in eachfigure.

The nature'of this invention relates to certain improvements in theconstruction of machines for planting Indian corn, and consists in thepeculiar construction and arrangement of the foot of each spout, forturning aside clods, small stones, and similar obstructions, for formingthe trench, and covering the seed dcposited therein; ina device formarking the place where each hill is planted in a novel and usefuldropper, for delivering the seed in regulated quantities to the spouts;

and in the peculiar arrangement of its various parts,

as hereinafter more tully shown and set forth.

In the drawing- A are traction-wheels, rotating at the ends of an axle,B, on which is secured the frame-work of the machine, and so arranged asto be drawn by animal power, the axle being of such length that thetrac- Lion-wheels will be the width of two rows apart, which is usually,if not universally, eight feet.

O is the frame, which consists of a pair of longitudinal bars at eachside, and a central bar, the whole united by suitable cross-bars, asshown.

a are spur-gears, formed on or attached to the inner faces of the hubsof thetraction-wheels.

'D is a shaft, journallcd in hearings in the frame parallel with theaxle. 3

I) are pinions, which have a lateral movement on the squared ends ofsaid shaft, and are simultaneously throwniu or out of gear with thegears a by means of the clutches a, lover (I, and crank e, and aclutchcollar on each, as shown in fig. 2.

When the pinions b are in gear with the spur-wheels a the shaft D isrotated.

E is a spur-wheel, rigidly secured to the shaft/D, and rotates a secondshaft, F, similarly journaled in the frame, through its pinion G.

f are pedals on the shaft F, by means of which the driver, sitting inhis seat H, may turn over the shaft with his feet, the machine being outof gear;

I are feed-spouts, flexibly suspended in the outer sides of the frame,and may be elevatcd, 'whende sired, to avoid an obstruction, by means ofthe treadles J.

K are seed-boxes, secured to the sides of the frame over the mouths ofthe spouts, with an opening in the rear part of each to the rear of themouth of the spouts, covered with a suitable slide, g.

Under each seed-box is secured a cylinder, L, with an opening in itsfront lower side leading to the spout nels as may be desired.

This dropper M is placed within the cylinder L, and is reciprocated by acrank on the end of the shaft F, through a suitable connecting-rod, It.In the reciprocation of the dropper it comes under the openingin theseed-box, when the opening in it will be filled with corn. In theadvance of the machine,

it moves forward in the cylinder, carrying the seed with it, until itcomes to the opening in the bottom of said cylinder, when the seed dropsinto the spout below. I

On the same crank-pin is secured a curved rod, N, its lower endsupported and guided by an eye projecting from the spout, and, as theseed is dropped and planted, it marks the spot on the ground.

t is a guard on the point of the spout, in the general form of a doublecultivator-shovel, its oflice being to turn aside clods of earth, smallstones, and similar obstructions.

j is a tooth at the extremity of each spout, which opens a furrow ortrench,in which the seed is dropped; and

It is a covering-plate, formed of a pair of wings,

either attached to or made part or" the spout, which,

by its construction and arrangement, will throw back into the trench theearth removed by the tooth, and thus cover the seed.

The dimensions and dispositions of the various gears and parts are suchthat, once in each four feet, a hill will be planted by each spout. I

In turning, at the end of the field, the operator throws the droppingdevices out of gear, and, after completing the turn, drives so that thewheel next the last planted row will track in the rut made by it.

This gives him the proper distance between rows, and dispenses with theusual preliminary marking of rows.

To make the rows parallel in the other direction, when he gets abreastof the line of rows, he plants the first pair of hills by turning overthe shaftv F, by

the pedals, and then throws the machine in gear, and.

proceeds as before.

\Vhat I claim as my invention, and desire to secure 3. The arrangementof the wheels A, the gears (1,71, Jy Letters Patent, is E, and G, theaxle B, the frame 0, the shafts D and 1. The guard 1', tooth j, andcovering-wings or plates F, the connecting-rod h, the markers N, theseed-drop- L', in connection with the spout-s I, as and for the purperM, the cylinder L, and the spout I, constructed pose set forth.substantially as described, for the purpose set 'forth.
